GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 253,167, dated January 31, 1882.

Application filed April 4, 1881. (ModeL) To all whom it may concern:

Be it known that I, CHRISTOPHER LIDREN, of La Fayette, in the county of Tippecanoe and State of Indiana, have in ented certain new and useful Improvements in Grain-Binders; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which form part of this specification, and in which- Figure l is a plan view of my binder; Fig. 2, a similar view with the platform, bindingarm, and its operating-lever removed. Fig. 3 is an end view; Fig. 4, afrontelevation, partly in section, of the binding end of the machine. Fig. 5 is an enlarged plan view of the binding or tying mechanism; Fig. 6, a reverse view of the tying-head; Fig. 7, a section through the same; Fig. 8, a view of the cord-holder; Fig. 9, a perspective of the gavel-carrier; Fig. 10, a side View of the rake, and Fig. 11 a detail of the stops for elevating it. Fig. 12 is a view of the knot. This invention relates to that class of grainbinders iii-which the gavels are bound by a cord which is passed around the gave], and then by means of tying devices tied intoa knot.

Theimprovement will be fully set forth in the following specification and then particularly pointed out in the claims.

A indicates the platform upon which the grain falls and along which the gavels are carried forward by the rake to the binding mechanism. This platform will be slightly depressed at a point under the binder-arm, and it is secured upon the main frame A, various parts of which frame will be hereinafter particularly described in connection with the devices supported by the same.

B refers to the rake, which is hinged upon a base, B, so that its teeth can be either raised to a vertical position, in which case they will project above the platform through the slots (1 a in the latter, or lowered to a horizontal position,'in which case the said teeth will be entirely below the platform. The base to which the rake is hinged is arranged to slide upon a way, I), that is secured to the main frame, the said way and the slots a in the platform being of a length sufficient to admit of the raketeeth, when raised, sweeping the platform and bringing the grain in gavels under the binderarm.

Pivoted to the base which carries the rake, and at the sides of the latter, are latches C 0, one at each side of the rake. The latch G is arranged to engage the rake, so as to hold the latter down in a prostrate position, while the remaining latch, G, is arranged to be brought under acam-piece, 0, upon the rake after the latter has been partially raised, so as to complete the raising of the rake and then hold the samein avertical position. A stop, 0, is socured to or formed with said cam-piece in order that after the rake has been raised the same will be prevented from falling forward or toward the binder-arm. This stop, it is evident, could be arranged upon the base with like effect.

In order to disengage the latch C from the rake and to raise the latter when it reaches the grain side of the machine, I provide a dog, 1), against which the said latch strikes just before the rake has reached the end of the platform, whereby the latch will be pushed away from the rake. I also provide a stop, D, against which oneof therake-teeth strikes, so that as the rake completes its travel it will be raised by the same; andI further provide a stop, D as seen in Fig. 11, which at this juncture will push the latch 0 under the campiece of the rake, so as to complete the raising of the rake, and lock the same in an upright position.

In order to push the latch O away from the rake in order to allow the latter to fall after having traversed the platform, so as to bring the gavel under the binder-arm, I provide a dog or stop,d, against which said latch strikes while the rake is being carried toward the binder-arm and I also provide a dog or stop, d, against which the latch G strikes after the rake has been pushed down by coming in contact with a portion of the main frame or platform, whereby said latch will lock the rake in a prostrate position. These stops or dogs that cause the'latches to operate in the manner described are all secured to the main framein any suitable manner.

The mechanism for impelling the movable base that carries the rake toward and away from the binder-arm consists ofa driving-skein or sprocket-wheel, E, upon one end of the shaft of which is a crank-arm, E, that is connected by a connecting-rod, E", with a lever, e, which in turn is pivoted at one end to the main frame, and atits remaining end connected with a crank, c, that is pivoted to the base-plate of the rake.

Thehiudingdevices and mechanism for operating the same are constructed as follows:

A crank, F, is secured to the axle of the d riving-skein E, and to this crank is connected a slotted bar, F, the slotfof which bar is at the end opposite to that connecting with the said crank. This slotted bar connects with a crank, G, that is pivoted to a standard, G, of the main frame by means of a wrist pin, g, of the crank that passes through the slot f of the bar. The wrist-pin g extends out from both sides of this crank, and upon one end of the said pin is arranged a loose collar, 9, to which is swiveled a connecting-rod, 9 the upper end of this connectingbar being swiveled to a collar, P, that is arranged loosely upon an arm, h, ofthe vibratory binder-arm H.

At the inner end of the slot of the bar F is a notch,f, adapted to engage the wrist-pin g, that passes through the said slotf. The walls of this slot act upon the wrist-pin of the crank G at certainintervals during the reciprocations of the slotted bar, and the said crank in turn actuates the swiveled connecting-rod that connects with the binder-arm, so as to cause the vibrations of the latter at the proper moments, as will be hereinafter more fully described.

The device which I employ for timing the movement of the crank G consists of a lever,

I, )ivoted to the said crank below the slotted end of the bar F, so that when the lever is vibrated in one direction one of its ends will strike against the said bar and raise the same, so that the notch in the slot will be raised to clear the wrist-pin on the crank. To the other or lower end of the lever H is pivoted a confulcrumpin of the lever and the point of connection between the lever and the slotted connecting-rod H When the slotted baris thrown forward to its farthest extent the wrist-pin on the crank will be engaged by the notch f at one end of the slot of said bar, and the lever II will assume a horizontal position; butafter the slotted bar has been retracted to a certain extent the combined action of the pin h upon the crank and the slotted rod B will cause said lever to assume a vertical, or nearly vertical, position, whereby it will act against and raise the slotted end of the bar F, so as to free the wrist-pin of the crank from the notch at the rear end of the slotfin the bar. This elevation of the bar occurs when the binder-arm is depressed, and afterthe rake has been thrown down and is about to travel away from the binding devices, all of which will be fully set forth in the description of the operation of the machine.

The binder-arm is mounted upon a shaft which has its hearings in the upper ends of two arms, I I, and from these arms rise two spring bars or arms, 2' t,which converge toward their upper ends, between which are arranged the tensionpulleys t 2'. These springarms are connected near their upper ends by a bolt,

6 that is provided with a nut, i ,wherehy said arms can be drawn together in order to vary the tension upon the cord that passes from the reel to and between the pulleys t" i, and thence down through eyes or over rollers i upon the binder-arm. One of these pulleys z" is provided with a hub, i and is mounted upon a shaft passing through the spring-arms,while the remaining pulley is mounted upon the said huh. Hence by drawing the spring arms together the pulleys will be brought more closely to each other, therebyincreasing the tension upon the binding-cord.

The mechanism for actuating the devices for holding, tying, and cutting the cord is constructed as follows:

K indicates a slotted lever, one end of which is connected with the crank of the-drivingskein or sprocket-wheel. This lever is reciprocated by the revolutions of said crank, and is guided in its movement by a vertical rod, K, that is secured to the main frame and extended up through the slot K of the said lever.

L refers to a vibratory lever, which is provided at a point near or at its center with a sleeve or hub, L, that is loosely arranged upon the vertical rod K, so as to turn freely thereon. This sleeve or hub is provided at its upper end with two horizontal arms, L L upon the end of each of which is a stop or pin, L At one side of the slotted end of the lever K is a stud or dog, l,arrangcd to act against one of the pins L upon one of the arms of the hub L; and on the opposite side of the said slotted end of the lever K are two studs or dogs, 1 arranged to act alternately upon the remaining one of the pins L, the dog 1 being extended farther out from the slotted lever than the dog 1 so as to insure such action. The vibratory lever L connects atits ends with the ends of a chain, M, by means of suitable links, the said chain being wound several times around the oscillatory shaft M of the tying mechanism. This chain is secured at a point between the ends of its coils to the sh aft, around which it is wound, so that a vibration of the lever L in one direction will cause the shaft to rotate one way, and "ibration of said lever in a reverse direction will cause a reversal of the movement of the shaft.

N indicates a many-armed rotary cord-holder that is pivoted to the main frame below the platform in position to hold the binding-cord which passes down from the binder-arm, and N indicates a notched arm that is pivoted to one of the ends of the lever L, so that at certain periods in the operation of the machine said pivoted arm will engage one of the arms of the holder and impart a partial. revolution to the same, so as to cause the end of the cord to be griped between the holder and the plate or frame upon which it is arranged. The shaft M carries the devices for tying the knots in the binding-cord, the construction and arrangement of which will be as follows.

P indicates the sliding cutter and holder, which, after the cord has been passed around the gavel, severs the same above the armed holder N and holds the ends of the cord until the knot has been tied. This said device con sists of a bar provided at its forward end with a hook, P,one inner edge, 12, of which is sharpened to form the cutter, and the other inner edge, p, of which is rounded to constitute the cord-holder. This bar is arranged to slide in a longitudinal channel, 19 in the shaft M, the said channel extending through a socket, 19 at one end of the shaft, so that the hook-shaped end of the bar can be extended out from said socket in order to catch the cord, and also retracted within said socket, so as to sever the cord by means of its cutting-edge, and to firmly hold the cord between the gave] and said socket by means of its holding-edge. The holder and cutter bar is caused to travel back and forth in the channel by means of a link, 12, that is pivoted to the sides of the oscillatory shaft, and arranged to act against studs 12 19 upon the cutter and holder bar. This link is vibrated by means of a link, 1;, connecting the same with a collar, Q, arranged to slide upon the oscillatory shaft, and the collar is caused to have such sliding movement at the proper moments by means of an arm, L, of the leverL, said arm having a wrist-pin, L that passes through the slot q of a bar, g, which is pivoted to one end of a vibratory yoke-bar, The arms of the y oke g ofthis bar engage in the circumfer; ential groove of the collar Q, whereby, While the vibrations of the yoke-bar will cause the collar to move along the shaft, the collar will also be permitted to partake of the oscillatory movements of the said shaft upon which it is arranged. This shaft is, in addition to the groove in which the cutter and bolder bar works, provided upon its opposite side with a longitudinal channel, R, in which is arranged the slidable grabber-bar R, which carries at its outer end the pivoted hooked grabber R The grabber-bar is connected with the link 1).

preferably by the same pin that connects said link with the link 1), although any suitable connection may be madebetween the grabberbar and either of the links, which, when the links are actuated, will cause the grabber-bar on one side of the oscillatory shaft to move in a direction reverse to that in which the holder and cutter bar on the opposite side of the shaft grabber-bar, and when the said baris projected out from its sheath the hooked end of the pivoted grabber-linger will be moved downward and backward by means of a stop or pin, 4, that is arranged across a channel, r This channel 1' is parallel with the axis of the oscillatoryshaft, and is formed between the walls of plates 1' N, which are provided with slots r 1 arranged so that,in ett'ect, a channel intersecting the channel 1' is formed. When the grabber-bar is retracted the notched end of the grabber will be elevated, so as to come in position to catch or grab the cord near its ends, which are held by the holder, as more fully described fart-her on.

In order to push the loop from the end of the oscillatory shaft at the proper moment, I provide the arm S, which is arranged to slide alongside of the shaft and fastened to the cutter and holder bar, sov as to move back and forth with the same.

T indicates the carrier for discharging the bound gavel. This carrier consists of a fork hinged upon a carriage, T, which is arranged to slide upon a way or track, T curved at its rear end. The carrier is moved back and forth by means of a cord or chain, 25, that passes around the several pulleys, t t, and connects with the movable carriage or base-plate of the rake. This cord is connected with an arm, t of the carrier, so that when the cord draws upon the carrier, so as to cause the same to carry the gavel to the discharge end of the platform, the carrier will be raised vertically,

but when by a reverse movement of the rakecarriage the cord or chain draws upon the carrier, so as to move the same back to take a fresh gavel, the said carrier will be swung down upon its carriage, so as to readily pass under the bound gavel.

The chute upon which the bound gavels are carried can be extended to any distance and at any angle of elevation, whereby, after the direct action of the carrier upon the gavels has ceased, the same will be pushed along by the succeeding gavels, which will be directed against them by the carrier.

The operation of this machine is as follows: The rake being raised so as to project above the platform, and being locked in such vertical position by means of one of the pivoted latches upon the rake-carriage, it is impelled toward ,IOS

IIS

the binder-arm by means of the system of I20 rotary holder N, which holds the end of the cord. When the rake reaches the point at which it is stopped in its movement toward the binder-arm the latch which has held it up is released from the rake by coming in contact with one of the dogs or stops upon the main frame, and the rake thrown down upon its carriage by coming in contact with any suitable stop upon the main frame or the platform. At

this juncture a slight continuance of the forward movement of the rake-carriage will bring the latch, which holds the rake down, against a dog or stop, which causes said latch to lock the rake in a prostrate position below the platform. The binder-arm is brought down at the proper moment to carry the cord around the gavel by the backward movement of the slotted bar F, the notch f in the slot of which engages the wrist-pin upon the crank G, which in turn actuates the binder-arm through the medium of the swiveled connecting-rod 9 As the shaft of the driving-skein or sprocketwheel continues its rotation the rake will he carried from the gavel to the opposite end of the machine, where by reason of the stops or dogs the latch will be freed from the rake, the rake then raised in position to again traverse the platform, and the latch that locks the rake in an upright position be brought into engage ment therewith.

After the binder-arm has been brought down in the manner just described the pivoted lever H will be turned upon the crank G by reason of the pin h upon the crank and the slotted bar H, which connects with said lever, so that the upper end of the lever will strike againstthe slotted bar F and raise its slotted end,so as to free the wrist-pin ofthe crank from the notch in said bar. Hence as the bar F continues to move backward the crank will remain stationary, since its wrist-pin will bein that portion of the slotwhich has pl'anewalls. Atthisjunctureone of the dogs or studs upon the slot-ted bar K strikes against one of the pins L upon one of the upper arms L of the hub or sleeve L, and gives a partial rotation to said hub,whereby a partial revolution will be given to the vibratory lever L, so as to cause the arm N, that is pivoted to said lever, to act upon the rotary cord-holder N, in order that said holder will take hold of the cord brought down by the binder-arm. Hence after the gavel has been bound, the knot tied, and the cord severed below the knot, the end of the cord passing down from the binder-arm will be retained by the holder and the cord be ready for a fresh gavel. The above movement of the lever L also causes a backward rotation of the oscillatory shaft carrying the tying devices through the medium of the link and chain connections between said shaft and lever, whereby the cord between the gavel and the holder N will enter the slots 1" at the end of the oscillatory shaft M, and thus come between the hookshaped end of the cutter and holder P and the sheath in which said hook-shaped end is retracted. The vibration of the. lever L also causes the sliding holder and cutter to be retracted within the sheath after the cord has been thus caught by the hook of said cutter and bolder, said movement on the part of the latter being efl'ected by reason of the action of the pin upon the center arm, L, of lever L against the slotted bar g, at one end of the slot thereof, which said slotted bar actuates the pivoted y0ke-bar q, that in turn causes the collar Q to slide upon the oscillatory shaft and thereby operate the links p 12 between the collar and the sliding holding and cutting bar. As this bar is being drawn into the sheath the cord between the same and the armed rotary holder will be severed by the cutting-edge of the hook-shaped end of the bar, while the ends of the cord between said bar and the gavel will be held between the sheath and the holdingedge of the cutter and holder.

By reason of the pivoted link 1), which acts against the studs p of the cutter and holder bar, and which is pivoted to the grabber-bar B, said grabber-bar will be extended out from the oscillatory shaft on which it slides when the cutter and bolder bar is retracted, as above described. Hence as the grabber-bar is being thus extended the notched finger or grab ber R which assumes an upright position while the bar to which itis pivoted is retracted, will be depressed by contact with the pin or stop 7, so as to catch and hold the cord near the ends which are held by the cutter and holder. The oscillatory shaft which carries the said grabber and cutter and holder will now be rotated forward by the action of oneof the studs or dogs of the lever K upon one of the pins L on one of the arms of the sleeve or hub L, and at the proper moment after the loop has been formed the cutter and holder will be moved forward and the grabber-bar retracted, whereby the cord will be released from the cutter and bolder and also from the grabber or notched finger. It will be seen that as the arm S moves with the cutter and bolder bar it will push the loop off from the end of the oscillatory shaft.

The movement of the carrier T for carrying the bound gavels from under the binder-arm is effected by means of its cord or chain connection with the rake-carriage, the said carrier being held upright while discharging the sheaves by means of the tension of the cord upon its arm in one direction, while said carrier will be depressed when it returns to the front of the platform by reason of the tension of the cord upon its arm in an opposite direction.
